The Liteon AP900 is an electronic cruise control system designed for newer vehicles. There is no mechanical actuator — speed is controlled via a rheostat.

The AP900 works with the vehicle's analogue signals (ACC, brake, clutch, speed signal in analogue form). 

If the vehicle uses CAN signals, it would be more practical to use the CAN-compatible model AP900Ci, which significantly simplifies installation.

The cruise control consists of three components:

• 1 – Main module
• 2 – Control module for adjusting speed
• 3 – Vehicle-specific wiring harness

The vehicle-specific T-wiring harness connects between the AP900 module and the vehicle's accelerator pedal using a Plug & Play connection (model-specific connectors). 

For vehicles with a manual gearbox, a clutch pedal sensor may sometimes also be required.
